GDS supplies high pressure water pump and hammers for the sensitive construction of the Solna United office building

For the sensitive construction of the Solna United office building, more than hundred holes for installation of sheet wall were to be drilled for Skanska Fastigheter. The drillings included pre-drilling for jet-grouting, drilling for grout curtain, pre-drilling for installation of dowel as well as drilling of RD casings for anchoring. In order not to harm the sensitive jet columns, air DTH was not possible to use. The water-propelled drilling was regarded as the most benign and efficient method. Read more project cases

GDS supplies WAI 40i hammer technology for the Chancza Water Reservoir in Poland

Commissioned by RZGW Kraków, the Polish contractor SOLEY needed to drill more than 300 drainage holes in order to prevent water filtration from eroding the body of the Chancza reservoir. A high rate of penetration (ROP) and precision drilling was needed and therefore the water-powered drilling techcnology from GDS/DrillKing was used. The project resulted in that the earth barrier was sealed off and the length of the path of it could be extended. Read more project cases

Project Case The Light Rail Line - Drilling for ground stabilization

In 2015, Foundation Drilling Sweden was appointed to drill 160 casing advancing holes, installing RD Ø220 drilled steel casing piles, for ground stabilization of the Stockholm Light Rail Line. The task was to drill while influencing the surrounding and ground with a minimum of vibrations. DrillKing’s water-propelled drilling hammer WAI 60i, delivered by GDS, was here used since drilling with air, close to the surrounding sensible buildings and cars, would have been too risky damaging them. As well, GDS also rented out the GDS 490 Diesel Pump (490 lit/min @ 200 bar) for this project. Thanks to the water-propelled drilling solution, the project was realized without unnecessary costs for covering the surrounding house façades and without risking surrounding cars in car park to be affected.
